Ibrahim Mubarak, a co-founder of Portland's Right 2 Dream Too and Dignity Village homeless communities, began his trial Tuesday in Multnomah County Circuit Court on charges of trespassing and interfering with an officer.

Mubarak requested the jury trial on charges stemming from an incident under the Burnside Bridge in downtown Portland Feb. 27. The trial is expected to last at least through Wednesday. Mubarak pleaded not guilty in February.

At least 15 of Mubarak's supporters gathered outside the courthouse Tuesday morning and filed into the courtroom with Mubarak to show their support.

Mubarak's lawyer, Kenneth Kreuscher, declined to give an opening statement and declined a reporter's request for comment outside of court until the trial is over.

Mubarak's arrest occurred while he and others were checking on people sleeping on the sidewalks in a parking lot near the University of Oregon's White Stag Building and Mercy Corps headquarters.

When news of his Mubarak's arrest surfaced in February, so did a video taken by a spectator. The video shows Mubarak's interactions with officers and his arrest. The video was posted to Right 2 Dream Too's Facebook page.

At least of a portion of the video will be shown to the jury as evidence.
